lbv all 'whom 'it cloacem:

vBe. it known that I, GUsrAvE O. DEGENER,

a citizen of the iUnited 'States,.residing in `NewYork cit in thevcounty vof'NeW York ew York, liave invented cerjputingfMachines,of.which the followingis a specification. l d This invention relates tothe tens-carryinginechanisinof computing devices, particularly thoseoffthe kinddisclosed -in the applications of -l-Valter VIight, No.185,046,

tiled March 22,- 1909,.anclfl\o. 543,693, tiledv -February '.12 1910, inwhich a constantlyv v revolving device i is called' upon inter- 'f-Amittentlyto assist incarrying tens from one computing wheel to thenext. As 'set forthfi'ii said app1ications,.each main computing '.wheel.is provided' with a special tooth,

' 20' whicl i turns a pinion that in mesh with 'the Vcomputing wheel ofnext- 'higher de- "poin-ination, toi `the end that said' higher'tcomputing-,n'fheel .may make one-tenth of a revolution- The movement ofthis tensl carrying piiiionis Vassisted by a constantly 1. revolvingsoft-rubber roll; the pinion having as'et of points 'or lobesl to engagesaid rollito be Vturned thereby, whereby sutlicient assistance to thetens-carrying pinion as- Surfed.

The object of the present invention is to -improve the construct-ion andoperation of thetens-carrying devices, with' a view to in- `cre se 'thespeed and reliability of action,

S5 and prolongthe life'of the parts.

' According' vto thepresent im rovements, in place of the soft-rubberrol aforesaid, there is employed a set of yieldingly .mounted pinionshaving line teeth adapted 40 to engage teeth-provided upon the-assisting lugs lixed to vthe aforesaids'tenscarrying pinion.Normally,=the constantly revolving pinion is out of mesh with vthe teethon said assisting lugs; but at the proper` time the movement of the maincomputing wheel .will cause one of said assisting spurs or l Vlugs tomesh withthefconstantly revol'ying pinion', whereby; the latter isenabled tof assist 'in the turning ofthe tensfcarrying' 5 0 pinion.ASince the constantly revolvingpinions f areyielding'ly mounted, theyVare sure to' mesh properly `with the teeth of the aforel saidassistin-1u'gs, since they will yield if I the lug teet -are improperlypresented to theiil. r

Fig. 12 is a separate View'of the pinion seen at Fig. 1l.

Each .primary computing wheel'l is inthe form 'of a gear inI mesh with agear 2, the latter fixed upon a number Wheel 3. AEach computing wheel lhas a series of ten interior notches 4;, whereby it is rotated. Therotation is effected by an interior master wheel 5, having oppositeteeth 6 working in the notchesl 4;; said master wheel fixed upon a shaft7 rotated by a gear 8. Intermittent variable rotation ofthev gear Siseffected o r controlled by keys in any suitable manner, as for instancein the manner illustrated in said applications. The gangs of computingand number Wheels travel step-by-step, to enable the master wheel 5 tooperate consecutively upon the primary computing wheels 1,. as set'forthiiisaid a plications.

Once in each revolution of eachprimary computing wheel 1, a specialtooth 10 thereon, sets in motion a tens-carryingpinion 11, which is inmesh with the primary wheel l of next higher denomination, whosediameter is twice that of thepinion; said pinion being providedforthis'purpose with a set of five equally spaced Aprojections 12. 'en-10 pinion .11 iid of thev nexthigher computing wheel l'is'a'ssisted orin part effected by one of a series of constantly revolving auxiliarypinions 13; the pinion 11 being provided,

. Vfor 'this purpose, with a series of ive spurs or lobes 14,. formingan auxiliary Wheel; the tipsof the lobes or points 14 having teeth'orfserrations 15 to match those ofthe pinion 13. A'detent roll 16 isseated in one of -five notches- 17 .between the points or lobes 14.{Said roll 16 is carried on an arm 17, pivoted at 18, and held by acompressionfspring 19, occupying a fixedftube or housing 20 and having ascrew adjustment. The movement of the tens-carrying pinion 11 originallyeffected by the special tooth 10 of the computing Wheel, is sufficientto bring a point or lobe 14 into mesh with the auxiliary pinion' 13.Since the latter isv in constant motion, it ivill operate to drive thepinion 11 positively in the same direction i until the latter completesits movement through one-fifth of a revolution. The movement of thetens-carrying pinion 11 is completed by said detent roll 16, and theteeth 15 are 'carried out of mesh with 13, the latter normally occupyingone of the recesses 17 as shown. The pinions 13 are spaced at intervalsalong a constantly revolving shaft 22, extending along the'g'ang oftens-addingl pinions 11, said shaft constantly rotated by any suitablesource of power as set forth in I said applications. The-shaft 22 ispreferably square or prismatic in cross section,.

and has a soft rubber covering 23 in the form of a tube, square incross-section; the pinion 13 having a square central hole 24,

. vto tit upon the cushion 23. This member 23 is of such consistency orAthickness as to yield very easily, so that, when the first of theadvancing teeth 15 on the star or Inutilated Wheel is struck by one ofthe teeth of the 'revolving pinion 13, the latter is enabled to yield,in order to prevent injury to the teeth. and also to prevent the teethfrom becoming inter-locked, and to insure that the pinion 13 will meshproperly with thc teeth 15. The square. or prisiniitic form of theshiitt und the cushion thereon, to

vvwhieh'the square' or non-circular central perforntions 24 in thepinions are fitted,

insures thiit the pinion will nli'vnys he positively rotated withoutliiihilitv of. injiii-.vuoti'he cushion and withoutintei'tering with theAyielding 65 action of the pinion.

by the shaft und its cushion,

'carrying device In the form' of the invention shown at Figs. 3 and 10,the pinion' 13 is mounted? on a round shaft 25, corresponding with 22,

and having a round tubular soft rubber tube ,26 secured to the shaft andto the pinions,

which have round bores to fit on said cushion. 4 .At Fig.' 3, thepinions 13E* are separated by vyashers 27 at intervals to agree with.-the se aration o f the star wheels .14; and it will be understood thatlthe pinions 13 may.

4be similarly separatedby .ring washers 28, 'Fig.111,
